Project overview

Long live The Queen! If you ever wanted to capture one of the most recognizable tones that rocked the biggest stadiums all over the world, here’s your chance!

Introduction

Our Queen offers a certain combination of the legendary Rangemaster pushing the preamp of a classic AC30, but with the tubes swapped for a more size-friendly JFET transistor.

The Queen is capable of producing amp-like tones with minimum effort. With only 3 knobs (gain, tone, and volume), you can be sure to dial in the perfect tone and just focus on your playing. This pedal reacts great to your playing dynamics as well as the volume knob on your guitar, so it gives you a broad palette of sonic possibilities without even touching the pedal itself!

With the gain control, you can make the pedal sound like a clean AC30 for those rhythm parts and then roll it to 10 for maximum sustain on your lead parts. It can get angry and aggressive, yet chime-y and beautiful at the same time.

The tone knob, which is based around the treble control of the AC30, gives you the ability to dial in just the right amount of high frequencies, whether you’re using a guitar equipped with humbuckers or single-coil pickups.

We will rock you? Hell yes, we will.
